FILING DEVICE.

Application filed December 22, 1926. Serial No. 156,447.

This invention relatesto 'filingdevices, more particularly toimprovements in the Construction and function of. filing devices as commonly employed for filing letters, invoices, and the like. 1

It is among the objects of the invention to provide a filing device of simple, durable, mechanical construction embodying a mini mum number of parts which shall be adapted to be manufactured by a few simple punching and bending operations whereby the cost of manufacture is reduced to a minimum. p I a The subject matter of the present invention relates to that type of filing devices which is used for temporary filing of paper sheets in large numbers such as bills, invoices or the like and accordingly the device is designed to permit the frequent addition and removal of papers from the file In the accompanying drawings constitutingapart hereof and in which like reference oharactersdesignatelike parts, Fig 1 is a top plan view of apa-per file embodying the principles of this invention; Fig. 2 is a longitudinal sectional View partly in elevation taken along the lines 11-11, Fig. 1; Fig. 3 a vertical sectional iew taken along the centerline IIL-III of Fig. 1; Fig.4: a development view of the metal base; Figs. Sand 6 elevations of a movable. lock and stop member located in the base in the manner and forthe purpose as. will be hereinafter set forth; and Figs. 7 to 10, inclusive are views illustrating a covermember or name plate used to cover the central opening of themetal base.

Referring to the several figures of the drawings, thestruct'ure therein illustrated comprises a. sheet metal. base 1 adapted to he mounted'and secured to aboard or support 2by screws 3 or in any other suitable p p strain this member agamst movement.

manner.v I

As shown in the developmentview of Fig. 4., the base 1 comprises a single sheet metal punching provided with openings 4 and 5, a pair of elongated openingsG, a central opening 7, an ,upstruok portion 8 and cutout portions 9 the latter having slots 10. The punching is formed or punched, out to provide for-folding the side portions 11 along the, dotted line 12 and end portion 13 along the dotted line 14. One of the side portions 11 also carries a slot 10, similar to and aligned with slots in members 9. The end portion 13 is provided with a lug 15 having an opening 16 therein to constitute an eyelet by which the filing device may be supported fi'om .a l1ook=or nail.

The cut-out portions 9 formedin the central'opening' 7 are bent along the lines 17 in the same direction as are the side. portions 11 and the end portion 13, thus forming a pair of lugs. The front portion is bent along, lines 19 and 19 forming a dopressed horizontal portion 19; and the sides of this portion are formed by bending .its

periphery along line. 18 in the same direction assides 11 and 13, as shown in Fig. 3.

.The lug 15 is bent along line 15*in themed ncr apparent from Fig. v3.

As shown in Figs. 2 and 3 a rod20 having a pair of curved retaining arms terminating at 21 and having its axial portion offset asshown in Fig. 2 to form an arm having a notch 22is disposed in the slotted opening 6 of the base by projecting the ends and bent upwardly along lines 23 and outwardly along lines 23 to form a skirt and flange, is used 'to secure member 20 1n its assembled position, as shown by Fig. 2. The

notches 23 engage shanks 20 of retainmg member 20 to hold thelatter firmly in notchesQ. After assembly, strap 23 is fastened tobase 1 as by spot welding, soldering or riveting. p

' A spring rod 25 is disposed in the 'depres sions 8 of the'base asshown in Figs. 1 and 2 and'in thisposition it engages the notch 22 of retaining member 20, to yieldingly re- In its closed position thearms of member 20 are at the front end ofinotches 6,*and it is movable only within the limits of these notches, as may be seen froinFig. 1. i The effect. of using the inclined notch in connecspring, whereby said spring frictionally resists the opening and closing movements 01" said retaining arms.

3. A filing device comprising in combination a one-piece sheet metal base, a pair 01 filing posts projecting upwardly through openings in said base and constituting the receiving element for the material to be filed, a retaining element consisting of a 10 pair of integrally formed curved upwardly projeoting rods pivotally mounted in said ba'se and adapted to engage the tops of said filing posts, means for yieldingly restraining the retaining elements against pivotal movement in said base, and means for locking said retaining element in the position of its engagement with said filing postsip In testimony whereof, I sign'my name.
